Filming officially began today in Jodhpur, India on Christopher Nolan's third Batman film, The Dark Knight Rises and, thanks to local scoopers, the first bits of information have started to trickle out from the set.

Most intriguing is the below shot of a "pool" of green screen. Fan speculation has already started, suggesting that the pool could be related to Ra's al Ghul's Lazarus Pit. In the comics, the character bathes in a mystic pool with rejuvenatory properties. The green color of the "pool" in the photo is almost certainly so that it can be replaced in post-production with a special effect of some kind.

Meanwhile, posters at The Dark Knight Rises Community have spotted Josh Pence on-set in Jodhpur, suggesting that, Lazarus Pit or not, Al Ghul will certainly be featured in the scenes in India.
